Spatter can originate from rapidly expanding gas bubbles in the weld puddle or in the metal drops that transfer from the end of the electrode. Expanding gases can cause drops to explode like an ...

Incorrect welding parameter; arc voltage, wire feed speed, welding current, stick-out, shielding gas flow rate and torch angle all need to be optimised.. Spatter is made up of many thousands of ...

The concept of welding is not new—people have been merging metals together using a plethora of techniques since the 1880s. While technology and protective gear has dramatically improved since then, ...
